A large midstream terminal in the Gulf Coast needed a solution to reduce the cost and time to degas a large 188’ diameter internal floating roof crude oil tank during tank maintenance activities. The tank degassing process included vapor control during the roof landing, draining, and blinding process followed by manway degassing to bring the tank interior to below 10% LEL in accordance with their TCEQ permit requirements. The client’s tank degassing vendors had used large amounts of propane during previous tank degassing projects.
